Abstract: Fractures of the extremities require appropriate splinting and it is recognized that splinting should be applied at the scene of the injury before the patient is moved. Ergo the emergency traction splint hereof as a part of first aid equipment which may be readily assembled into operating position at the site of an accident for first echelon service while the injured person is removed from the scene and brought with injured limb in traction to a hospital for treatment at a higher echelon, which splint may be readily disposed of, once it has served its emergency purpose. The splint serves to hold longitudinal traction on a broken femur or a hip dislocation. That is, it has a capacity for obtaining and holding a pulling action on the injured leg.

Abstract: Belt 21 on which a residual filter cake has been formed by the action of a suction box (16, FIG. 1) on a slurry, is brought over a filter grid 46 superimposed on a membrane 42 inflation of which causes the filter cake to be compressed upwards against stationary pressure plate 53 for further dewatering. The grid 46 has parallel grooves in its top surface and further parallel grooves in its under-surface, and intersecting with and communicating with those in the top surface, to permit suction to be applied by way of suction pipe 146 and drain duct 45. The belt 21 is intermittently driven, but the arrangement may be such that the belt moves continuously and the grid 46, membrane 42 and pressure plate 53 move in sequence, forwards from a starting position for a certain distance in contact with the belt while applying pressure to the filter cake and then backwards to the starting position out of contact with the belt.

Abstract: Slurry required to be filtered is supplied to a downwardly inclined feed section of intermittently-moving belt 25 by way of supply pipe 20. Inclination of succeeding vacuum section of belt 25, over vacuum boxes 17, ensures even distribution of thin layer of slurry over belt 25, dependent upon angle of inclination, in range 4.degree. to 20.degree. to horizontal (an angle of 8.degree. being illustrated).Subsequently resultant filter cake layer is subjected to mechanical dewatering by an expansible membrane of a lower pressure plate 23 being expanded to press belt 25 with filter cake thereon against underside of counterplate 24.

Abstract: A hydraulic logsplitter assembly including a logsplitting mechanism and comprising means for charging logs thereto consisting of:a boom,a support mechanism supporting the boom and disposed at an angle from the vertical centerline for facilitating the free swinging of the boom at an angle from on an inclined plane under the weight of a load between charging and discharging positions,a base for rotatively supporting the support mechanism,a torsion spring interconnecting the base and support mechanism for the swinging returnably of the boom from discharging to charging position,a cable supported by the boom,a grapple unit mounted at the free end of the cable.

Abstract: A two-part composite insulated masonry building block assembled as to both of its parts at the site of manufacture and transportable in assembled form to the construction site and including, as a first part, a block of concrete or other cementitious material having spaced outer and opposite side walls together with a trio of spaced transverse webs connecting between the side walls and defining a pair of equal cells or cavities, with at least two of the webs being provided with tapered air gaps or thermal breaks extending upwardly from the lower horizontal plane of the block, and as a second part, a longitudinally-extending insulative element of molded polystyrene or other suitable rigid foam material being complementarily configured with strategically-located tapered slots extending downwardly for the seating of the insulative element between and in general parallelism with the block side walls and into the tapered air gaps in interdigitating relationship and defining additionally an insulation capacity at ea

Abstract: A vehicle body comprises a pair of swingable doors giving access to a load carrying interior of the body. To facilitate opening and closing of the doors a coupling mechanism links the doors for simultaneous counterbalanced movement.

Abstract: In a glassware forming machine, a non-handed transfer mechanism, for transferring freshly-formed hot glassware, by swinging through a right angle about a vertical axis, from a dead plate to an adjacent conveyor, comprises a side-by-side parallel pair of rams having pistons on the free ends of which is a pusher plate. A piston stop bar is located centrally of the pistons and is connected to a piston tie plate for arresting the pusher plate and pistons at the end of an extending stroke of the pistons.

Abstract: A method of recovering tin from tin dross consisting of positioning a barrel having an apertured bottom and charged with a supply of the tin dross upon a partitioned collecting tin mold, with the components thus arranged being placed into a furnace for subjecting the components and tin dross charge to a temperature approximating 700.degree. F. for a time duration approximating 5-6 hours and allowing the developed molten free tin to flow downwardly of the barrel and through the apertures thereof and into and between the partitions of the collecting tin mold, and withdrawing the collecting tin mold for cooling before removing the cast tin bars therefrom. The apparatus aspect relates to the design of the barrel and collecting tin mold.

Abstract: A board game includes an upright playing surface representative of a mountain having trails or paths thereon with openings for releasably receiving playing pieces, there being missiles or other hazards slidably or movably related to the mountain and which are adapted to strike the playing pieces to physically knock them off of the mountain.

Abstract: An acetabular prosthesis comprises a body 41 of plastics material defining a part-spherical socket cavity 43 surrounded by a rim 44. A flange extends outwardly from the rim 44. At 48 it inclines from the rim 44 in the direction of the body 41 and at 49 it inclines from the rim in a direction away from the body 41, while lobes 46, 47 therebetween are correspondingly curved. This arrangement provides for a considerably increased area of bone in the acetabulum to be available as a cementing surface when the prosthesis is fitted into a reamed out hip acetabulum in the special circumstances of the invention which is that the axis of socket cavity 43 extends substantially transversely with no or little anteversion.

Abstract: An acetabular prosthesis for use in an artificial hip joint. Because acetabula vary in size, it is not practicable to produce a single prosthesis for each acetabulum, being preferable to provide a blank which can be manually trimmed to fit each acetabulum. Here a blank is used in the formation of an acetabular prosthesis comprising a body surrounding and defining a part-spherical socket whose entrance is surrounded by an annular rim and having a flange extending outwardly and rearwardly from the periphery of the rim and made of a material capable of being manually trimmed to be asymmetrical. The flange may be marked with cutting lines to indicate where it should be trimmed to fit a left or right acetabulum.

Abstract: Bearing components, such as cages, rings, retainers, washers, spacers and the like, are formed from flat stock strips in preference to the employment of known methods of blanking same from stock having a dimension as great or greater than the larger dimension of the end product.

Abstract: A housing attached to and swingable with a vehicle sun visor accommodates primary, secondary, and tertiary auxiliary visors which are selectively withdrawable through appropriate housing slots into extended positions leftward of, rightward of, and downward of the housing, respectively.
